On a serious note, does anyone actually think it's possible to make 'irl p0rtal lawl 1337' ?

Do you understand me?When you make sometihng like this

What happens when i grab it,and rotate it.

It's quite simple really (after you sit there and think about it for a few hours). The bottom of the pole would move in the opposite direction to the top of the pole, and you couldn't really rotate it at all if you had welded it. But you could rotate it slightly if it was attached using sticky tape. In the first picture imagine there is sticky tape connecting each side to each other, I forgot to put the tape in the zoomed in image. The second picture shows that each end has been welded.

MS paint ftw

heh wouldn't the poll be falling down, even if you connect it, at terminal velocity?

you'd have to keep it from moving by connecting something to it somewhere.

As I posted many pages ago, Larry Niven did some serious thought about this.

Anyone seriously interested in this might also want to dig up a copy of "The Theory and Practice of Teleportation" by Larry Niven. It's an essay collected in All the Myriad Ways which attacks teleportation in many different aspects, the most rigorous being with a system with an "entrance" and an "exit" that mirrors the circumstances of Portal very closely.

He comes to some very interesting conclusions. For example, if you dropped anything into an infinite portal series (ex a portal on the roof and floor that line up), what you end up with is something that rapidly reaches terminal velocity. Remove the air and it continues to accelerate until it reaches a considerable fraction of the speed of light and begins to gain mass that eventually becomes gravitationally significant and throws the Earth out of rotation.

Of course, the only place this could be carried out would be the North or South Pole, because otherwise whatever was passing between portals would drift due to the Coriolis Effect and there would be no way to keep it going into the transmitter.

(Due to relativtity, nothing can travel at the speed of light. As an object accelerates closer to the speed of light, it gains more mass. As a result, a constant force could never accelerate an object to light speed. Basically, momentum is velocity times mass. So to have a force (e.x. gravity) acting on an object, therefore increasing its momentum, and if velocity can't reach the speed of light, then mass has to be the thing that increase.)

Thanks Hobs.

There was lots of stuff back there that was a bit to much for me at the time of posting, or I probably would've noticed.

Explain to me why exactly rotating one part of the pole would cause the other "half" to rotate the other direction.

As far as I can infer from your drawings, and from portal physics themselves, even the orientation of the portal itself doesn't change how it rotates around it's Z axis. Any other axis, then yes, the portal orientation DOES matter, but.. uh.. You could twist that pole as much as you wanted.
